Clock for Your Second Monitor
Turn the screen you are not using into a beautiful clock. This clock for a second monitor gives an idle display a job: a large, glanceable time source you can read from across the desk without touching your main screen. No install, no account — open it on the second monitor, press fullscreen, and it is done.
Why a Second-Monitor Clock?
Most people check the time by reaching for a phone or covering their work with a clock widget. A dedicated clock on a second screen removes both problems: the time is always visible, and your main screen stays for work. It is the difference between interrupting a task to check the time and simply glancing sideways.
Setups That Work Well
- Dual-monitor desk: clock on the secondary display, work on the primary.
- Laptop + external monitor: put the clock on the laptop screen while you work on the big one.
- Vertical / portrait monitor: a large flip clock fills a portrait screen elegantly.
- Spare tablet or old display: any device with a browser becomes a desk clock.
- Study desk: a calm clock for tracking sessions without a phone in reach.
How to Set It Up
- Open this page in a browser window on the second monitor.
- Drag the clock to centre it on that screen (or use the Dock's “Center clock”).
- Press
F11(or use the fullscreen button) to fill the second screen. - Pick a theme or background so it suits the room.
- In your OS display settings, disable sleep for that monitor if you want it always on.
Choose Your Style
A retro flip clock suits a creative desk; the digital clock is cleaner for a work setup; the analog clock is calmer for study. For a pure, chrome-free display, see the fullscreen clock. To time tasks on the main screen, open the timers.
Frequently Asked Questions
Can I open a clock on only one of my monitors?
Yes. Open the page in a browser window on the monitor you want, then press fullscreen — it will fill that screen only.
Will the clock keep running when I am using the other screen?
Yes. The clock runs continuously in its own window and keeps accurate time even when it is not the focused tab.
How do I stop the second screen from sleeping?
Fullscreen helps, but screen sleep is an OS setting. Turn off display sleep for that monitor in Windows, macOS or Linux display settings.
Does it work on a vertical monitor?
Yes. Drag or resize the clock to suit a portrait screen; large digits fill the height well.
Do I need to install anything?
No. It runs in your browser. Once the page has loaded it works offline too.
